Your Baby's Development

Your baby's brain continues to develop, and tiny fingernails and toenails start to form. Vocal cords are formed this week, which is the last of your first trimester.

Your baby's kidneys are functioning! After swallowing amniotic fluid, your baby will now be able to pass it out of the body as urine. And the intestines will make their way into the abdomen, since there is room for them now.

Your Body

Has anyone told you that you have that "pregnant glow"? It's not just the joy you may feel because you're having a baby — there's a physiological reason for smoother, more radiant skin during pregnancy. Increased blood volume and pregnancy hormones work together to give you that glow. The greater blood volume brings more blood to the blood vessels and hormones increase oil gland secretion, resulting in a flushed, plumper, smoother skin appearance. Sometimes, though, the increased oil gland secretion can cause temporary acne.
